Cheapest Electricity in Texas 2026: City-by-City Rate Comparison Guide

Texas has the largest deregulated electricity market in the United States — and the most competitive. With over 100 licensed retail electric providers (REPs) competing for your business across the ERCOT grid, Texas consumers have more choice than anywhere else in the country. But with that choice comes complexity: rates vary significantly by city, by zip code, and even by the time of year you shop.

This city-by-city guide breaks down what Texas residents in the major metros are paying for electricity in 2026, which providers tend to offer the best rates in each market, and how to lock in the cheapest rate available at your address.

How Texas Electricity Deregulation Works

Most of Texas — everything on the ERCOT (Electric Reliability Council of Texas) grid — is deregulated. This covers the vast majority of the state including Houston, Dallas, Fort Worth, Austin, Waco, Killeen, and most other major metros. Notable exceptions include El Paso (served by Xcel Energy and not deregulated) and parts of the Panhandle and Rio Grande Valley served by non-ERCOT utilities.

On the ERCOT grid, your local transmission utility (Oncor, CenterPoint, AEP Texas, or TNMP) delivers power and handles outages. Your Retail Electric Provider (REP) is who you buy the electricity from — and that’s the competitive, shoppable piece.

Houston: Cheapest Electricity Rates 2026

Houston is served by CenterPoint Energy for delivery and has one of the most competitive REP markets in the state. Because Houston’s distribution area is large and densely populated, nearly every major REP offers plans here.

Average fixed rates available in Houston (2026): 10.5–13.5 cents/kWh for 12-month plans. Look for plans in the 10–11 cent range during non-peak shopping periods (spring and fall). Top REPs competing aggressively in Houston include Reliant Energy, TXU Energy, Direct Energy, Gexa Energy, Rhythm Energy, and Chariot Energy (for 100% solar).

Houston tip: Watch for “bill credit” plans — many Houston REPs offer significant monthly bill credits (e.g., $75 off if you use 1,000–2,000 kWh). At high usage levels, these can effectively bring your net rate below 10 cents/kWh. Read the Electricity Facts Label (EFL) carefully to understand at what usage level the math works in your favor.

Dallas / Fort Worth: Cheapest Electricity Rates 2026

The DFW Metroplex is served by Oncor for delivery — the largest transmission utility in Texas. Competition among REPs is intense, and Dallas-area consumers generally have access to slightly lower rates than Houston due to different delivery charge structures.

Average fixed rates in DFW (2026): 10–13 cents/kWh for 12-month plans. Strong competitors in this market include TXU Energy (largest REP in Texas by market share), Gexa Energy, 4Change Energy, and Payless Power for no-deposit prepaid options.

DFW tip: Oncor’s delivery charges are some of the lowest in Texas, which means your total bill cost depends heavily on the generation rate you lock in. A low fixed rate here translates more directly to savings than in some other territories.

Austin: Cheapest Electricity Rates 2026

Austin is a split market. The City of Austin is served by Austin Energy, a municipally owned utility that is NOT deregulated — meaning residents inside Austin city limits cannot shop for a different REP. However, surrounding areas in the Austin metro — Cedar Park, Round Rock, Pflugerville, Kyle, Buda, and others — are served by Oncor or PEC and ARE on the deregulated ERCOT grid.

If you’re in an Austin suburb on Oncor: Average fixed rates run 10–13 cents/kWh. Gexa Energy, Rhythm Energy, and Green Mountain Energy are popular choices in these zip codes.

San Antonio: Cheapest Electricity Rates 2026

Like central Austin, San Antonio is served by CPS Energy — a city-owned utility — and is NOT deregulated. If you live inside San Antonio’s CPS Energy territory, you cannot shop for a different REP. Some communities on the far outskirts of the metro may fall under AEP Texas Central, which is deregulated.

Corpus Christi & South Texas: Cheapest Electricity Rates 2026

Corpus Christi and the South Texas coastal area are served by AEP Texas Central for delivery. This is a deregulated territory with solid competition. Average fixed rates: 11–14 cents/kWh for 12-month plans. REPs like Reliant, TXU, and smaller regional suppliers like Frontier Utilities serve this market.

How to Find the Cheapest Rate at Your Specific Address

Texas rates are zip-code specific because delivery charges vary by transmission utility territory. The only way to see the exact rates available at your address is to enter your zip code on a comparison platform. Here’s what to do:

1. Enter your zip code on a licensed REP comparison site or marketplace
2. Filter by contract length — 12-month fixed is usually the best starting point
3. Check the EFL (Electricity Facts Label) for the “average price at 1,000 kWh” — this is your true apples-to-apples comparison number
4. Look for hidden fees — base charges, minimum usage fees, and early termination fees can all affect your real cost
5. Enroll online — most Texas REPs process switches in 1–3 business days with no service interruption

Specialty Plan Types Worth Knowing in Texas

• Prepaid electricity (no deposit): Available from providers like Payless Power and GridPlus. No credit check, no deposit — you pay as you go. Rates are typically higher but the flexibility may be worth it.
• Free nights/weekends plans: Several REPs offer plans where electricity is free during off-peak hours (typically nights 9pm–6am or all day Saturday/Sunday). Great for households that can shift usage.
• 100% renewable plans: Chariot Energy, Green Mountain Energy, and Rhythm Energy specialize in solar and wind-backed electricity in Texas at competitive rates.
• Month-to-month plans: Variable rate with no long-term commitment. Rates fluctuate monthly — higher risk but maximum flexibility.

Bundle Internet and Security with Your Energy Switch

While you’re shopping your electricity, it’s a smart time to also look at other household services. Texas is one of the best states for bundling energy with competitive internet and home security — providers like AT&T Fiber, Xfinity, and Frontier all compete heavily in the Houston and DFW markets. Pairing a new energy plan with a Vivint smart home and security system that includes a smart thermostat can also help you make the most of your lower electricity rate by reducing consumption automatically.

Bottom Line

The cheapest electricity in Texas is never just one provider — it’s the right provider for your city, your utility territory, your usage level, and the current market conditions. The good news is that competition is fierce year-round, and switching is fast and penalty-free when your contract term ends.
